Moldavite is a member of the Tektite group, a glassy mixture of silicon dioxide, aluminum oxide and other metal oxides, with a hardness of 5.5 to 6 on the mohs scale. Its formation coincides with the crash of a large meteorite in what is now the Bohemian plateau of the Czech Republic, approximately 14.8 million years ago.
